The questions are what is the null and alternative hypothesis? statistic test, p value, reject or fail to reject null hypothesis and why, confidence interval, and conclusion. thanks

The "Freshman 15" refers to the belief that college students gain 15 lb (or 6.8 kg) September 54 75 49 65 68 63 57 67 63 during their freshman year, Listed in the accompanying table are weights (kg) of randomly selected male college freshmen. The weights were measured in April 56 82 50 68 64 64 61 66 65 September and later in April, Use the listed paired sample data, and assume that the samples are simple random samples and that the differences have a distribution that is approximately normal. Complete parts (a) through (c). a. Use a 0.05 significance level to test the claim that for the population of freshman male college students, the weights in September are less than the weights in the following April. In this example, u. is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the April weight minus the September weight. What are the null and alternative hypotheses for the hypothesis test? Ho : Hd Hi Pd kg (Type integers or decimals. Do not round.)
